The guy is trying to make money off the backs of others, I seriously he got permission from the mod's authors, otherwise he would have listed them in a copyrights/contribution document like I did for Zini's Ultima TC.

Exactly. We'll so how this goes. What I don't like is the name, because people might confuse it to be linked with the OpenMW project somehow. I guess it's nothing illegal about it since open source and all, but it's still kind of unethical if you ask me.

What is this, really now? A modpack? He seriously wants money for a modpack?

Pre-OpenMW it wasn't possible to ask for money for a modpack as Bethesda owned the rights to anything the CS had touched. Now our open-source construction set exists (because apparently XEdit tools like TES5Edit don't count and people regard Bethesda as still owning the rights to mods made with them) people don't have to care what Bethesda think, so there'll be people trying to grab money any way they can, even if they end up violating the rights of modders (as modders are less likely to take legal action than Bethesda).

It looks like the author of this project is forum user TimMB (he was also the one who added it to the OpenMW Wiki). So it looks like he is able to respond to these threads directly.

I went ahead and downloaded the project to see what it was. It's 2.3 GB of mods, all in .omwaddon format. It includes the official Bethesda mods and over 200 other mods. The readmes for all the mods are included in a folder. It also includes the original Morrowind music, but no other game assets that I could find.

The stated goal is as follows:

In this project I am correcting: meshes, textures, broken quests, misconfigured scripts, incorporating derived community modding works directly into the patch to reduce the number of patches needed and selectivly improving graphics.

Not a bad goal, but I couldn't find any indication that he had gotten the permission of the original mod authors, much less any agreement to make money through their work.

The author also has a GoFundMe, Patreon, and PayPal connected via NexusMods, which I won't link to so as not to encourage search engine traffic. The Kickstarter is the latest of these fundraising methods. I have no idea what the legalities are regarding making money with mods, but I suspect that making money through a modpack of others' mods isn't okay.
